So you are basically saying you would not take Halladay and Fielder because of losing out on Castro, Lawrie might be a very good player and Halladay is 34? Not me...I take Fielder and Halladay. A first or second round 1b and the best SP in the game imo. I can live with Rollins. The other guy takes the risk on Lawrie and Castro. Somrtimes you can get caught up on age in a keeper. The idea is to win. Fielder is 28 and Halladay is an elite SP with enormous value down the road for the next couple of years. Worst case you deal him in the next couple of years for another younger top player. And Rollins should retain decent value at SS so you should be able to move him for something as well. The only way barring injury you lose this deal imo is if Lawrie turns in Bautista and Castro turns into Tulo. Anything is possible but I do not see Castro becoming that elite\developing a lot of power.
